just found out, what the reason was and "solved" it. The message is misleading. "actively refused it 127.0.0.1..." is not right. There is nothing active refusing. In my case just the ccnet service was not running, because I did the test direct after installing. The windows service installs as a manual service and was not started.

So I guess in your case it is also a not started service or, perhaps, a firewall blocking that network connection.
